Trichloramines

ALS can test for trichloramine is produced as a byproduct from the reaction between chlorine and nitrogen compounds.

ALS can test for trichloramine is produced as a byproduct from the reaction between chlorine and nitrogen compounds. In an indoor swimming pool environment, use of chlorination to sterilize the water can react with nitrogen from urea and other organic nitrogen sources (creatinine, amino acids etc.) to produce a mixture of chloramines. Due to trichloramine's low solubility in water, it is released into the atmosphere where it can become concentrated in poor ventilated areas. Patrons can experience irritation of the eyes and mucous membranes. Long term exposure can potentially lead to asthmatic symptoms.

ALS developed an air method under contract with NIOSH to captured and detect both Hypochlorous acid (including mono-/ dichloramine) and Trichloramine in air. Samples are collected using a sorbent tube/ treated filter combination in series with a personal sampling pump.
